IN KIN G MECHANISM FOR PRINTING MACHINES.

Application led October 13, 1919. Serial No. 330,225.

T 0 all whom t may concern.'

Be it known that 1, soAR RonsEN, a citi- Zen of the United States,residing at New York city, county of Kings, and State of New York, haveinvented certain new and useful .improvements in Inking Mechanism forPrinting Machines, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

`This invention relates to improvements in inking mechanism for printingmachines and is designed particularly for use with the type of inkingmechanism shown in United States Patents No. 1,214,856, February 6, 1917and No. 1,311,198, July 29, 1919, both to Bruce C. White. j

1n the type of inking mechanism shown in these patents, ink is suppliedthrough a series of separate conduits, one conduit being provided .foreach column or other desired section of the form to be inked, and theink is delivered under pressure to the conduits and in regulatedquantity. by a plurality of pumps, one pump being provided for eachconduit. 1n this inking mechanism there is provided a reservoir locatedadjacent the distributing cylinder or the form cylinder, or othersurface to which the ink is to be forced. The pumps are located in thisreservoir and mea-ns are provided for independently varying theadjustment of each of the pumps, so that the supply of ink de livered toeach column or other section of the form may be varied as desired. Theseadjusting devices are located closely adjacent the pumps, being as shownin these patents, in the reservoirs, and the adjustment is effected bythe operator at the reservoir.

Where two or more printing couples are employed, as in the large rotarymulticouple machines, each couple is provided with one of thesereservoirs and the inking mechanism contained therein then brieflyreferred to. 1n the making of adjustments, therefore, the operator hasto move around the machine from one couple to the other to make hisadjustments. 1t is desirable,

therefore, that means be provided whereby A the pumps of all thereservoirs may be adjusted ,from a central point which may be located atany convenient and desired part of the machine, as for instance, thefolder, whereby the pressman when not satisfied with the character ofprinting as the web reaches the folder can adjust the necessary inkpumps to the required or desired degree and inking of any particularcolumn or section which may require such regulation. 1t is furtherdesirable that an independent adjustment of the ink at or adjacent thepumps be maintained so that an adjust-ment can be made there.

It is the especial object; of the present invention to produce an inkingmechanism for printing machines, each couple when more than one coupleis employed being provided with an inking mechanism embodying separateconduits, one for each column or other section of the form, with meansfor feeding ink tothe conduits, and a central controller station locatedat a distance from the ink supplying means for adjusting or regulatingthe quantity of ink supplied from the conduits. A further object of theinvention is to produce such a construction which will combine a distantadjustment with an adjustment close to or adjacent the printing couple,and a further object of the invention is to produce an etticientconstruction for such purpose which comprises as small a number of partsas possible and of simple character, so as not to readily get outoforder.

Vith these and other objects not specifically referred to, the inventionconsists in certain novel parts and combinations, which for a fullunderstanding thereof will be described in connection with theaccompanying drawings in which Figure 1 is a diagrammatic side elevationof a Vtwo couple printing machine embodying the invention. in apreferred form.

Figure 2 is a side View partly in section and partly broken away alongthe distrib uter, showing the arrangement of the conduits as they comefrom the reservoir.

Figure 3 is a detail sectional View showing a form of nozzle which maybe used for distributing the ink on the distributer.

Figure 4 is a detail sectional view on an enlarged scale through one ofthe reservoirs.

Figure 5 is a similar view, partly broken ioo away, showing the drivingmechanism for `operating the pumps.

Figure 6 is a det-ail sectional View of part of the controlling oradjusting mechanism which is located at a distance from the pumps. v

Referring now to these drawings, the invention has been illustrated asemployed with a rotary printing machine having two printing couples,each of which is provided with a reservoir in whichv operate the inkpumps and a control station located at the folder. lt will beunderstood, however, that the invention has been designed for and may beused with a single couple machine and that the control station may belocated at a point in the machine other than the folder, if so desired,and with other feeding devices.

In these drawings, one of the printing couples includes the form andimpression cylinders 1, 2, with the distributer 3 and a train of inkdistributing rolls 4, this couple being inked'from a 'reservoir 5. Theother couple includes the impression cylinder 6, form cylinder 7,distributer 8, and train of ink rolls 9, this couple being inked fromthe reservoir 10. After printing the web W is led to a folder 11 of anysuitable character and at the folder are positioned the controlstations, preferably one for each reservoir marked 12 and 13.

The inking mechanisms employed are the same for all the couples, and adescription of one will suffice for all.

In the particular construction illustrated, each inking mechanism willinclude a reservoir 15 having a. top 16 and a bottom 17. The bottom ofthe reservoir is apertured to receive a plurality of ink conduits 18,the conduits extending through packing 19 so as to be ink tight. Theseconduits are provided preferably in such numbers that there is a conduitfor each column or other section of the form or forms to be inked, theconduits in the particular construction illustrated being-32, to ink 32columns. These conduits lead to the distributer as 3, being carriedbeyond the reservoir so as to be beneath the distributer as shown inFig. 2, in a frame or box 20, one wall of which is formed with adistributing nozzle indicated generally at 21 by which the ink isdelivered to the distributer or other ink receiving surface. While thenozzle shown in Figs. 2 and 3, is the preferred one, it will beunderstood that the ink may be delivered from the conduits to thedistributer in any desired manner, and with any desired form of nozzle.

The ink is forced to the conduits in regulated quantities through aseries of pumps, one such pump being provided for each conduit. Thepumping mechanism may be of various forms and may be operated in variousways. One that has worked well in practice is that illustrated in thedrawings, in which there is provided in the reservoir a frame 22 mountedto have a sidewise sliding movement in suitable guides 23, one of whichis shown in Fig. 5. This frame is provided with suction and dischargeports 24, one of these ports being provided for each of the conduits 18.Working in the frame and in, each of these ports is a valveless plungerpump having a plunger in the form of a rod 25 which intermediate its endis provided with an operating collar 26 fast thereon. These pumps areoperated in any desired manner, being given a vertical movement forsuction and discharge. and the frame 22 is given a sidewise slidingmovement alternately to bring the ports 24 into communication with theink in the reservoir for suction and with conduits 18 for discharge. Asshown, this is effected by providing a second frame 27 having apertures28 through which work the upper ends of the plunger rods 25. This frame27 is grooved, preferably at two points, to receive eccentric shafts 29,30, which at their ends carry eccentric heads 31 fast on the frame 27.These shafts are driven in any suitable manner, as

from a power shaft 32 having a miter gear 33 meshing with a miter 34 ona short shaft 35. The other end of this shaft 35 carries an intermediategear 36 whichmeshes with gears 37 on the ends of the shafts 29, 30,before referred to.

Each of the `plunger rods 25 above the frame 27 is provided with aspring 38, taking between the top of the frame and a stop collar 39 faston the rod. The fra-mes 22 and 27 are preferably connected with eachother by a supporting rod or bar 40, through which the sliding sidewisemovement iis given to the frame 22. As the eccentric shafts rotate, theframe 22 is given a sidewise movement to bring the ports 24: intocommunication with the bottom ofthe reservoir. As the movement of theshafts continues the frame 27 is lifted and this movement raises theplungers through the springs 38 the extent of this movementdepending onthe position of certain stops hereinafter referredto. Any furthermovement of the eccentric is compensated for by the springs 38. As theshafts continue their further movement and the frame 27 starts downwardit contacts with the collars 26, before referred to, and as at this timethe frame 22 has slid sidewise so as to bring the discharge ports 24into line with the conduits 18, a further movement of the eccentriccauses the plungers to start to move down and force the measuredquantity of ink into the conduits.

In accordance with the invention, means are provided whereby the upwardor suction movement of the plungers may be varied so that they will takeup on the suction stroke a varying quantity of ink, and mea-ns will beprovided whereby this regulation of the plunger movement may becontrolled both at the pumps or at any other desired point of themachine, at a distance from the pumps. Various constructions may beprovided whereby this Imay be effected. In the particular constructionillustrated, the top 16 of the reservoir is formed with a plurality ofdownwardly extending projections 41 which are recessed to accommodatestops 42, the position of which limits the suction stroke of theplungers. These stops are in the form of sliding rods and in recessedportions of the projections 41 these rods are provided with springs 43taking against the bottom of the recessed portions of the projections atone end and against collars 44 fast on the rods at the other ends. Thetendency of the springs is to throw the stops up. This upward movementof the stops is limited by adjusting screws 45, these screws beingthreaded through blocks 46, and the screws provided with heads 47 bywhich they can be adjusted in the blocks so as to cause the stop rods 42to stop their upward movement at a desired point to provide for thenecessary suction stroke of the plungers. The plunger movement can thusbe regulated at the pumps.

Various constructions may be em loyed for effecting the regulation ofthe p linger movement at some point in the machine distant from thepumps. In the particularl construction illustrated, this distanceregulation takes place from the folder and at the folder there areprovided what may be termed controller stations from which theadjustment of the pumps may be effected. The particular means forcarrying out this may be widely varied, but inthe particularconstruction illustrated, it is effected by a movement of the adjustingscrews 45, before referred to. As shown, the blocks 46 are pivoted onstuds 48 and each block is provided with a downwardly extendingprojection or ear 49 in which is secured a mechanical connection leadingto the controller station, this connection, in the present instance,being a wire 50, one of these wires 50 being provided for each adjustingscrew. These wires 50 pass over suitable guide rolls 51 (see Fig. 1),which are preferably flanged to and over a flanged guide roll 53 at thecontroller, and these wires are operated from the controller in anysuitable manner to give them the required movement for operating theadjusting screws 45.

While various constructions of controllers may be employed, as shown,there is provided a box 54, it being understood that one of thesecontrollers is provided for each inking mechanism. This controller boxhas a top 55 which is apertu'red to receive adjusting screws 56, theseadjusting screws be'- ing the same in number as the adjusting screws 45,before referred to. Mounted in the box beneath t-he top thereof arebrackets 57 in which are pivoted on pivots 58 levers 59, one lever beingprovided for each screw. One arm of these levers, as 60, contacts withthe lower end of the adjusting screw 56. The other arm 61 of the lever59 is tapped to receive a screw bolt 62 held in position by locking nuts63, and the other ends of the wires 50 are attached to these bolts.

It will be seen that with this lconstruction by operating the adjustingscrews 56 the lever 59 is rocked whichin turn through the wires 50 rockthe blocks 46, thus moving the screws 45 downwardly thereby forcing thestops 42 downwardly and limiting the extent of the upward or suctionstroke of the plungers 25, so as to regulate the amount of ink suppliedto the particular conduit whose pump has been adjusted. On releasing theadjusting screws 56, the springs 43, on the stops 42 act to force thesto-ps upwardly to the position previously occupied by them before theadiustment was changed by manipulating the screws 56. A very simple andeflicient construction is thus provided for regulating the pumps fromany desired point in the machine. If desired the adjustment at the pumpsmay be omitted, but preferably, as before stated, thus adjusting meanswill be employed.

In the construction illustrated in the drawings, the pumps and conduitsare arranged, preferably as shown, in what may be termed sets, one setsupplying eight different columns or sections of the form, that is thesupply of ink necessary for printing one page. Machines constructed inaccordance with the invention may include devices whereby the inksupplied by each set of pumps may be simultaneously varied, so

that, if desired, the ink supply fora whole page may be simultaneouslycut down or increased. Constructions for effecting this result are shownin the drawings, in which each of the sets of pumps is provided withsuch an adjusting mechanism. As illustrated this adjusting mechanismcomprises a controller 65, one controller being provided for each setand being'identical in construction and manipulation. As shown, thiscontroller is in the form of a sliding frame or bar, the frame beingarranged to slide in ai groove or slot 66 iii a plate 67 mounted on thebottom 17 of the reservoir, before referred to. This controller 65 isprovided with ports 68 through which the maximum amount of ink to bedelivered by the pump may be passed to the conduits 18. The controllerframe is also provided with what may be termed by-pass ports 69 in theform of shallow grooves separated fromnthe ports 68 by narrow ridges 70.By shifting 130 Seil.;

this controller frame, as shown in Fig. 5,

the ports 68 and 69 are shifted relatively to the port 24, so that onlya portion of the ink passes from the ports 24C to and through the ports68 to the conduits,acertain amount of the inkbeing diverted through theport 69 back into the reservoir, the amount of ink thus diverted andreturned depending on how much of the area of port 69 is brought lintocommunication With the discharge port 24.

While the invention has been shown and described in its preferred form,it Will be understood that various forms of feeding mechanism may beemployed and various connections between the feeding mechanism and thecontroller station or stations Without departing from the invention, andit Will be understood that such changes and variations are Within thescope of the invention.
